Abstract (en)
[origin: US2016253011A1] Disclosed are a pixel circuit and a display apparatus. The pixel circuit comprises a pixel compensation module, a light emitting module and a touch detection module; the pixel compensation module is connected to a first to a fourth scan signal lines (Scan[1], Scan[2], Scan[3], Em), a first operation voltage (Vdd), a data voltage (Vdata) and the light emitting module respectively, and is configured to control the light emitting module to emit light for display in accordance with inputs from the scan signal lines; the touch detection module comprises a detection sub module and an output sub module. The pixel compensation module and the touch detection module are integrated into the pixel circuit, and the pixel compensation module and the touch detection module share the data voltage (Vdata) and the scan signal line in common.
